COMBINED LAMP-SOCKET AND SHADE-HOLDER.

Specification of Letters Patent.

Patented Sept. 17, "1907.

Application filed March 25,1903. Serial No. 149,466.

To all whom it may concern:

Be it known that I, JULIUs C. TOURNIER, a citizen of the United States, residing at Schenectady, county .of Schenectady, State of New York, have invented certain new and useful Improvements in a Combined Lamp-Socket and Shade-Holder, of which the following is a specification.

The present invention relates to lamp shade holders for incandescent lamps, and has for its object to provide a combined lamp socket and shade holder which shall ,be of strong and durable construction, attractive in appearance, less expensive to manufacture than the combined shade holders and sockets heretofore in use, and with the parts so related and connected that the shade will be supported in the same position with relation to the lamp as in the case of the standard detachable shade holder.

The invention will be more clearly understood by reference to the following description taken in connection with the accompanying drawing forming a part of this specification in which Figure 1 is a top plan of a combined shade holder and lamp socket embodying one form of my invention; Fig. 2 is a side elevation of an ordinary socket shell with a shade holder, shown in section, in position thereon, but not connected therewith; Fig. 3 is a side elevation of a complete socket with a shade holder, shown in section, connected thereto; and Fig. 4 is a part section of a modified form. 1

In the arrangement shown in the drawing the socket shell 1 is of the standard form and size, having a lower cylindrical section 2 of less diameter than the upper section 3 and provided in its upper edge with slots 4 and 5 for the reception of the switch key 6 and retaining screws 7 of the cap part 8. i

The shade holder 9 is made from sheet metal and comprises a conical web 10, and inner and outer cylindrical flanges 11 and 12 struck up from one side of the web. The inner flange 11 has an internal diameter corresponding to the external diameter of the lower cylindrical section 2 of the shell, so that the latter may be inserted in the former as shown in Fig. 2. The outer flange may be made with diflerent diameters according to the size of shade to be supported, and is provided with radial screws 13 for securing the shade in relation therewith. The web 10 may have apertures or slots 14 formed therein for ventilating purposes by cutting out segmental sections at intervals and leaving other sections 15 which constitute integral bridges or connections between the inner and outer flanges 11 and 12.

The socket shell 1 and the shade holder 9 are secured in fixed relation by placing the parts in the position desired, as shown in Fig. 2, and forcing or spinning projections or beads 17 and 18 simultaneously in the lower section 2 of the shell and the inner flange 11 of the holder, as shown in Fig. 3, whereby cooperating shoulders are formed in the respective parts to prevent longitudinal movement of the one relatively to the other.

It is apparent as indicated in Fig. 4 that the projection or shoulder 19 between the two sections of the shell I might be relied upon to prevent the movement of the holder upward with relation to the shell and that the projection or bead 17 formed in the shell might be positioned to engage the lower end of a short flange 11 to prevent downward movement and thereby obviate the trouble of forming the projection or head 18 in the flange 11.

It is to be noted that wherever the cooperating shoula metal shell, a metal shade holder consisting of a web and inner and outer flanges projecting from one side of said web, and cooperating shoulders formed on said shell and said inner flange whereby said holder is permanently secured in fixed position on said shell.

2. A combined lamp socket and shade holder comprising a metal shell having two cylindrical sections of different diameters, a metal shade holder consisting of a web and inner and outer flanges projecting from one side of said web, said inner flange being of a size to closely engage the smaller cylindrical section of said shell, and cooperating beads formed in said shell and inner flange whereby said holder is permanently secured in fixed position on said shell.

A combined lamp socket and shade-holder comprising a metal socket shell, a metal shade-holder having a web provided with a central flanged opening through which the end of the shell projects a substantial distance below said web, and beads for permanently securing said flange to said shell.

In witness whereof I have hereunto set my hand this 23rd day of March, 1903.

JULIUS C. TOURNIER.
